How to Configure SSL Certificates in Docker Vaultwarden

When setting up Docker Vaultwarden, securing your instance with a trusted SSL certificate is crucial for maintaining user trust and ensuring data security. In this guide, we'll walk you through the process of configuring SSL certificates for your Docker Vaultwarden installation.

### Understanding SSL Certificate Options

Before proceeding, it's essential to understand the different SSL certificate options available in Vaultwarden. You can choose from using a self-signed SSL certificate, a trusted SSL certificate from Let's Encrypt, or uploading your own SSL certificate.

### Generating a Self-Signed SSL Certificate

If you're testing Vaultwarden locally or don't have access to a trusted SSL certificate, you can generate a self-signed SSL certificate. To do so, specify 'n' when prompted and use the self-signed SSL certificate option, which is only recommended for testing purposes.

You will be asked whether it's a trusted SSL certificate (y/n). If you already have your own SSL certificate, specify 'y' and place the necessary files in the required location. For more information on using self-signed SSL certificates, refer to Certificate Options.

### Using Let's Encrypt to Generate a Free SSL Certificate

Alternatively, you can use Let's Encrypt to generate a free SSL certificate for your Vaultwarden instance. To do so, specify 'y' when prompted and enter an email address for expiration reminders from Let's Encrypt. Typically, this value should be the configured DNS record.

You will be asked whether you want to use Let's Encrypt to generate a free SSL certificate (y/n). If you choose 'y', you'll be prompted to enter your domain name for your Bitwarden instance.

### Uploading Your Own SSL Certificate

If you already have an SSL certificate, you can upload it to Vaultwarden. To do so, specify 'y' when prompted and place the necessary files in the required location. For more information on uploading your own SSL certificate, refer to Certificate Options.

In conclusion, configuring SSL certificates for your Docker Vaultwarden installation is a straightforward process. By choosing from self-signed SSL certificates, trusted SSL certificates from Let's Encrypt, or uploading your own SSL certificate, you can ensure the security and trust of your users.
